Cerebras Inference Chat Completions API

Cerebras 官方参考页定义聊天生成 POST API，需 Bearer API key，输入 model 与 messages，返回 choices、usage 和计时信息；支持流式及工具调用但参数受模型限制。费用、配额和数据保留未知，仅文档核对。

Published description

该接口面向聊天助手和多轮对话，按消息角色提交上下文并生成 completion。正文给出字段与响应参考，附件内嵌的官方 bash 示例明确完整 URL。本次只整理文档，不获取 key、安装 SDK、调用推理或执行返回的工具请求。

Inputs

  • 必填 model 字符串和 messages 数组；role 支持 system、user、assistant、tool、developer，文本或图像输入支持依模型。
  • 可选 stream、temperature、top_p、max_completion_tokens、reasoning_effort、response_format、tools 与 tool_choice 等。
  • Content-Type 支持 application/json 或 application/vnd.msgpack；可选 gzip Content-Encoding。

Outputs

  • 成功 200 响应包含 id、choices、created、model、object，以及 usage 和 time_info。
  • choices.message 可含 content、reasoning 或 tool_calls；finish_reason 包括 stop、length、content_filter、tool_calls。
  • stream=true 返回局部 message deltas；tool_calls 是模型请求，本次没有执行其所描述的函数。

Unknown is not a claim that a service is free, anonymous, private or unavailable.

Limitations

  • 当前 n 仅支持1；max_tokens 与 max_completion_tokens 是别名，不能同时发送。
  • 模型对 reasoning、图像、工具、输出格式及 service_tier 的支持有差异，不能把单模型样例推广到全部模型。
  • json_object 不兼容 streaming；seed 仅尽力稳定，不保证确定性。
  • 文档描述 service tier 和 quota 概念，但未给此账号的数值限额、价格或 SLA。

Unknowns

  • 真实 key 和账号/model 权限、数值限流、配额、价格及 SLA 未验证。
  • 消息/图像/缓存的保留期限、训练使用和隐私政策不在本附件。
  • 样例延迟与 token 数是文档样例，不是本次测试或性能保证。

Add a public correction or observation

Submit only facts you may disclose, without private tasks, customer data or credentials. Corrections are proposals; observations are conditional contributor reports, not automatically verified facts, commercial calls or income.

Propose a sourced summary correction

This form proposes a summary change for the current fixed version. Other supported fields use the original API. Concurrent version changes return a conflict.
